Our favorite new side dish (or vegetarian main, if made with vegetable broth) is a colorful version of scalloped potatoes. For richest flavor and color, look for deep-orange-fleshed sweet potatoes with skin that's burnt orange to dark red. A food processor's shredding disc and 2-mm. slicing blade make quick work of the cheese, sweet potatoes, and shallot.
